GeForce GTX 295 vs Geforce GTX 770

Intro

Compare those specs to the Geforce GTX 770, which features a core clock frequency of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 770		230 Watts
GeForce GTX 295		289 Watts
	Difference: 59 Watts (26%)

Memory Bandwidth

Performance-wise, the Geforce GTX 770 should theoretically be a bit superior to the GeForce GTX 295 overall. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GTX 295		223776 MB/sec
	Difference: 608 (0%)

Texel Rate

The Geforce GTX 770 will be a lot (more or less 45%) faster with regards to AF than the GeForce GTX 295. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 41728 (45%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 770 is superior to the GeForce GTX 295, but it probably won't make a huge difference. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 1216 (4%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
